Christmas morning a boy rides down the road on his brand new bike when a cop on a horse rides up beside him and says "Did Santa bring you that bike?"
"yea" the boy replies.
"Well maybe next year you can ask Santa to give you a helmet for that bike" and proceeds to write that boy up a 20 dollar ticket.
As the boy rides away on his bike he turns around and says to the police man "Did Santa bring you that horse?"
humoring the boy he says "sure"
"Well maybe next year you can ask Santa to put the dick on the bottom of the horse  instead of on top!"
